One of Gaddafi's sons admitted, that the allegations against the nurses were completely fabricated:
http://en.wikipedia.org/wiki/HIV_trial_in_Libya 10 August 2007, Saif al-Islam Gaddafi, son of the leader of Libya admitted that the confessions were extracted through torture with electric shocks and threats targeted at the medic's families, and confirmed that some of the children had been infected with HIV before the medics arrived in Libya
Imagine this: You travel to a foreign country with the best intentions, to help the people there who suffer under a ruthless and volatile regime and then you get abducted and tortured. You really think we should make friends with such a regime? Only last year the doctor and nurses were ravished by the Libyans in every imaginable way. Look, what happened to those poor medical experts:
"They tied my hands behind my back," she wrote. "Then they hung me from a door. It feels like they are stretching you from all sides. My torso was twisted and my shoulders were dislocated from their joints from time to time. The pain cannot be described. The translator was shouting, 'Confess or you will die here.
...
Ashraf Ahmad Jum'a, the Palestinian Intern, told Human Rights Watch “We had barbaric, sadistic torture for a crime we didn’t do,” “They used electric shocks, drugs, beatings, police dogs, sleep prevention.” The interview was conducted in the presence of a prison guard. “The confession was like multiple choice, and when I gave a wrong answer they shocked me,”<36>
Valentina Siropulo, told Human Rights Watch “I confessed during torture with electricity. They put small wires on my toes and on my thumbs. Sometimes they put one on my thumb and another on either my tongue, neck or ear,” “They had two kinds of machines, one with a crank and one with buttons.”
Kristiana Valceva, said interrogators used a small machine with cables and a handle that produced electricity. “During the shocks and torture they asked me where the AIDS came from and what is your role...” She said that Libyan interrogators subjected her to electric shocks on her breasts and genitals. “My confession was all in Arabic without translation,” ... “We were ready to sign anything just to stop the torture.”<36><37>
Lawyers for the accused medical personnel have asked for 5 million Libyan dinars (approx. 3.7M USD/3.1M EUR) as compensation. Much of the evidence is based on medical reports prepared by authorities from Bulgaria relating to marks and scars on the defendants.
